For proper ackerman, the tie rod end should fall on a line drawn from the center of the rear axle through the front lower ball joint. Looking at a front end with stock spindles and discs, this just isn't possible.

Also (correct me if I'm wrong here) the idler arm pivots and center link pivots should also fall on a line drawn from the center of the rear axle through the LCA pivot point.

So with the front-mount rack, it would have to be wider at the inner tie rod ends than the LCA pivots - the actual width depending also on how far forward it is. Correct ?

I'm wondering if its possible to overcome the ackerman issue by moving the rack further forward.

Does anyone know of a book that has good info on front end design?
